"One word says it all; WOW! What a package! The STaSIS gear turned a great car into an incredible super car!"

"By adding the Challenge Package, I was able to boost that performance and keep the car covered under the manufacturer’s warranty. On a recent road trip, I averaged better than 20mpg. The car accelerates like a demon, sticks like glue and sounds amazing! I don’t even listen to the stereo anymore. The exhaust is like a symphony! The car is great fun at any speed. I highly recommend STaSIS products. Challenge Package provides an excellent return on investment!"
